給して成膜する方法である。 There are two possible methods for producing such a chemical-resistant conductive film, one of which is a film forming method using an extruder. This method is further classified into two types; one is to mix resin pellets and carbon fine powder, which are to be the material of the film, in an extruder while melting the resin;
One method is to extrude to form a film.The other method is to melt the resin and mix it with fine carbon powder, make this mixture into pellets, and then feed the pellets to an extruder to form a film. .

フイルムを得る方法である。 Another method is to dissolve the resin that will become the material of the film in an appropriate organic solvent, add fine carbon powder to this to form a uniform resin solution, and knead it with a ball mill etc. to form a paint. This is a method of obtaining a film by applying this paint onto a base film that does not have adhesive properties, drying it to form a film, and then peeling this film from the base film.

ことができる。 In the former method using an extruder, the time from material supply to melting, mixing, and film formation is short, and sufficient kneading is not achieved, making it difficult for the carbon fine powder, which is a conductive filler, to be uniformly dispersed in the resin. A good conductive film could not be obtained. On the other hand, in the latter method of mixing fine carbon powder into the resin solution,
Since the resin is in the form of a solution, it is easy to mix the carbon fine powder, and the kneading time can be set freely, making it possible to sufficiently knead the carbon fine powder into the resin until it becomes uniform, resulting in good conductivity. It is possible to obtain a film having the following characteristics. Furthermore, since the film is formed by the coating method, it is not necessary to coat the film to the desired thickness in one coat; if the film is coated to the desired thickness in several coats, pinholes and Defects such as uneven thickness are eliminated, and a more uniform film can be obtained.

物性を持つたものがなかつた。 By the way, resins with excellent chemical resistance that can be used as materials for chemical-resistant conductive films include polyethylene, polypropylene, fluororesin, vinyl chloride,
Resins such as vinylidene chloride and polysulfone are considered, but they do not have good physical properties because they are difficult to dissolve in general organic solvents, and unlike vinyl chloride, a flexible film cannot be obtained unless a large amount of plasticizer is used. There was no one who could hold one.

定で、有機溶剤に溶けることが分つた。 The present inventors investigated various resins that meet the requirements for conductive films that are soluble in general organic solvents, exhibit chemical resistance, and have flexibility in the resulting film, and found that a resin made by chlorinating polyolefin In other words, chlorinated polypropylene, chlorinated polyethylene, chlorinated ethylene-vinyl acetate copolymer (hereinafter referred to as "chlorinated EVA"), etc. are stable against various chemicals such as acids and alkalis, and are organic. It was found to be soluble in solvents.

ングする恐れがあつた。 However, films produced by mixing conductive carbon fine powder into chlorinated polyethylene or chlorinated polypropylene have low flexibility, and tend to become harder and more brittle, especially as the degree of chlorination increases. On the other hand, a film made from chlorinated EVA was flexible, stretchy, and had rubber-like elasticity, but the surface of this film was sticky, and there was a risk that the films would block each other.

The inventors have discovered that it is possible to obtain a film in which there is no blocking between the films, and the present invention has been completed.

This is a chemical-resistant conductive film characterized by being a mixed resin consisting of 10 to 80% by weight of a combination and 90 to 20% by weight of chlorinated polyethylene or chlorinated polypropylene.

From, the degree of chlorination is 45

ができる。 First, chlorinated polypropylene and chlorinated polyethylene are dissolved in an organic solvent, and chlorinated EVA is added to this. An appropriate amount of carbon fine powder such as graphite or carbon black is mixed into this as a conductive filler, and the mixture is kneaded using a ball mill, attritor, etc. to form a coating liquid. This coating liquid is applied to chlorinated polyethylene,
Chlorinated polyolefins such as chlorinated polypropylene and chlorinated EVA are coated on a base film that has a property of being difficult to adhere to, by reverse roll coating, knife coating, etc., and dried to form a film. The chemical-resistant conductive film of the present invention can be obtained by peeling it off from the base film.

Since the film is used as an adhesive, the resulting film has improved flexibility, exhibits rubber elasticity, and has improved strength as a film. Furthermore, the degree of flexibility can be freely controlled by adjusting the mixing ratio of chlorinated EVA.
